Title: Portable luggage carrier.
Inventor: BAKER FRANKLIN W
IPC: B62B3/02
Filed: 1983-07-12
Abstract: A portable luggage carrier (10) having a resilient mounting surface (24) to accept hand luggage, with castors (48) and (50) providing mobility and weight receiving characteristics. A structural frame (20) provides a rigid mounting surface and attachment for the castors (48) and (50) that are retractable into the frame body (20). A flexible towing strap (52) with a slideable buckle (54) is interposed with the frame (20) and encompasses luggage that is juxtaposed on the mounting surface. The strap (52) is tightened with the buckle (54) and the remaining end becomes a hand held towing strap. A securing latch (36) is spring loaded into the retractable member (25) or (26) to lock the castors in either the extended or retracted position. The preferred embodiment includes a removable cover (61) that slips over the carrier exposing the handle through a slot in the cover. In another embodiment the carrier comprises a combination brief case and cover (73). In still another embodiment a hinged back cover (62) encloses the carrier (70).

Title: Well logging sleeve and method for making same.
Inventor: MORE HENRY SANCTUARY
IPC: E21B47/12
Filed: 1983-09-19
Abstract: A replaceable insulating sleeve (20) is disposed around the lower end of a drill string (29) used in drilling a well. The sleeve (20) is restrained from rotating relative to the drill string (29), but can be released and quickly slipped off the drill string in the field to permit rapid replacement if damaged, or if alternate equipment is required. The sleeve carries sensing means (34) for measuring a characteristic of formations penetrated by the well. Anchor means (122) on the sensing means prevents it from rotating relative to the sleeve.
Patent EP-0154641-A4 (EP)
Title: Fluid handling device.
Inventor: ROSAEN NILS O
IPC: F16K15/06
Filed: 1984-08-15
Abstract: A fluid handling device which operates as a combination check valve and fluid flow meter. The fluid handling device comprises a housing (10) having an inlet (22), an outlet (28), and a fluid passageway formed therebetween. A valve seat (26) is contained within the housing in series with the fluid passageway while a valve member (40) cooperates with the valve seat and is movable between an open and a closed position. A compression spring (50) urges the valve member towards its closed position so that whenever the fluid pressure at the outlet exceeds the fluid pressure at the inlets, the valve moves to its closed position thus preventing reverse fluid flow through the device. Preferably, a tapered surface (56) on the valve member forms a variable area opening at the valve seat which increases in area as the valve member moves from its closed and towards its open position. An indicator needle (86) is mechanically connected to the valve member to produce an exteriorly visible signal of the position of the valve member which, in turn, is representative of the fluid flow rate through the fluid handling device.

Abstract: A transmission-economized serial bus protocol comprising at least one eight-bit word further comprising at least an operation code and a subargument (Fig. 2). The operation code and subargument comprise, respectively, either a start-of-message character or a start-of-reply character and either a device destination address or the device's source addresse (Fig. 3). Further, an error detection device is provided comprising an even parity bit.

The prioritization comprises a constant time delay plus a bit-time delay proportional to an accessing device's address identification (Fig. 5). Finally, there is provided an optimized method of inter-device (120, 140, 150, 180, 190, 200) message addressing and handshaking in a multi-access, bussed system, each device having a source and destination address, comprising addressing a message to a destination address and awaiting the addressed destination device to acknowledge by echoing its corresponding source address and also monitoring the bus (230) for an announcement of a source addressed event and performing a function accordingly.

Patent EP-0329681-A4 (EP)
Title: Database usage metering and protection system and method
IPC: G06Q30/04
Filed: 1987-10-08
Abstract: A "return on investment" digital database usage metering, billing, and security system includes a hardware device which is plugged into a computer system bus (or into a serial or other functionally adequate connector) and a software program system resident in the hardware device. One or more databases are encrypted and stored on a non-volatile mass storage device (e.g., an optical disk). A tamper-proof decrypting device and associated controller decrypts selected portions of the stored database and measures the quantity of information which is decrypted. This measured quantity information is communicated to a remote centralized billing facility and used to charge the user a fee based on database usage. A system may include a "self-destruct" feature which disables system operation upon occurrence of a predetermined event unless the user implements an "antidote"-instructions for implementing the antidote being given to him by the database owner only if the user pays his bill. Absolute database security and billing based on database usage are thus provided in a system environment wherein all database access tasks are performed at the user's site. Moreover, a free market competitive environment is supported because literary property royalties can be calculated based on actual data use.
